摘要： A method and a system for displaying images are provided. In the method, a pixel is provided that includes a layer of ferroelectric material and a layer of liquid crystal material. A first electric field is momentarily applied to the pixel to electrically polarize the ferroelectric layer to a first polarization. The first polarization is then used to maintain the liquid crystal material in a first orientation corresponding to a first apparent brightness of the pixel.

摘要： The pen input device has both a movement detection system and a position detection system that collectively track the position of the pen input device during a writing operation on a writing surface. The pen input device has a writing tip capable of performing a writing operation in contact with the writing surface. A controller is operable to activate the movement detection system continuously during the writing operation and to activate the position detection system intermittently during the writing operation. The movement detection system is operable to determine movement data that represent changes between successive positions of the writing tip. The position detection system is operable to determine position data that represents a position of the writing tip on the writing surface.

摘要： A display device for providing optical feedback includes light sources, each for emitting light in a different respective wavelength range, electro-optical elements defining pixels of an image, each for selectively passing light in one of the wavelength ranges and a sensor for measuring the intensity of light output from a portion of the electro-optical elements. To provide the optical feedback, a controller activates one of the light sources, alters those electro-optical elements within the portion of the electro-optical elements that are arranged to pass light in the wavelength range of a select one of the light source and reads out the measured intensity from the sensor. Based on the measured light intensity, the controller adjusts an illumination parameter associated with the select light source.

摘要： A frequency modulated (FM) vertical cavity surface emitting laser (VCSEL). The frequency modulated VCSEL includes a mirror region that has an active region. The frequency modulated VCSEL also includes a phase adjustment region for use in altering the characteristics of the VCSEL. For example, by changing the index of refraction in the phase adjustment region, the wavelength of the VCSEL can be changed, resulting in frequency modulation.

摘要： A semiconductor color sensor implemented without the use of color filters. Fabricating photodiodes using different semiconductor materials provide photodiodes with different sensitivities vs. wavelengths. A first embodiment uses photodiodes with different junction depths. A shallow junction depth produces a photodiode with its sensitivity peak in shorter wavelengths, while a deeper junction depth produces a photodiode with its sensitivity peak in longer wavelengths. Amorphous as well as crystalline structures may be used. A second embodiment uses photodiodes with different materials, such as Silicon-Germanium (SiGe) which has a longer wavelength peak sensitivity, and Silicon (Si) which has a shorter wavelength peak sensitivity in comparison. More than two photodiodes having different wavelength sensitivities may be used. Sensing current ratios between pairs of diodes allows color balance to be maintained.

摘要： An optical waveguide such as an optical fiber extends across a semi-rigid substrate or optical back plane and is made of conformal materials having indices of refraction selected to provide substantially total internal reflection of light transmitted within a core. An optical pin is made of substantially rigid optically transmissive materials. A receptacle in the substrate or optical backplane removably receives and holds the optical pin to allow a beveled terminal end of the pin to penetrate the core of the optical fiber to establish a gap-less interface that provides an optical path between the core and the pin.
